後部座席のシートベルト着用義務化に関する縦断的研究 Longitudinal study of the use of rear-seat belts
In this study, a survey was conducted concerning the use of rear-seat belts, which had been made obligatory by the Road Traffic Law of 2008. The research involved a longitudinal study using five points in time, from before the use of rear-seat belts became obligatory until the 2010 crackdown on failure to use them. Rates of use of rear-seat belts and awareness of their importance (risk estimation) were both raised after the law went into effect. For all items, the main effects were seen by seat position, and for two items by period.
